About this 1.73ct natural heart diamond

This 1.73ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 260000051781. Listed at 10 retailers as of November 4, 2026, with prices from $10,238 to $18,552, a $8,314 spread on the same certified stone. NZ Jewellers lists it at $18,552. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
